Airlines especially need crews to grow! And there is a major shortage of experienced pilots, Ryan has been hemorrhaging experienced pilots to other carriers that offer more.
Perhaps true, but there is also a perceived idea that RYR had an alleged predatory philosophy & business model that caused the demise of competition thereby creating a supply of desperate workers who would work for any T's & C's they could get. Hence RYR could expand into vacuums, of their own creating, very cheaply. Very capitalistic and dog eat dog, survival of the finest and live by the laws of the jungle. Thus they had no need to raise incomes, indeed they have been effectively reduced.
Perhaps that is starting to change. We shall see.
